By now, I’m sure you’re all familiar with Singer Vehicle Design, the niche California-based builder of absolutely stunning, restomodded, vintage Porsche 911s. Actually, Singer doesn’t like the term “resto-mod,” but prefers calling its creations “the perfect interpretation of what a Porsche 911 should be.”

Anyway, yes, the cars do in fact look damn near perfect, and now, the company is at it again with this: the Dynamics and Lightweighting Study.

Heart of Williams The idea spawned from one of Singer’s customers who requested a weight reduction and performance modification package for their 1990 Porsche 964. Singer liked the idea, and instead of simply taking the car in the shop for some basic tuning, went a little further. Much further. It contracted a partnership with none other than Williams, yes, Williams, the formula 1 development team, in order to collaborate on the project. Insane? Just the right term, if you ask me.

What began as a simple customer request quickly morphed into a full-fledged, high-caliber engineering project. Williams and other partners released a variety of new designs aimed at making the Porsche 964 faster, lighter and handle better. The most significant of these designs is an all-new 500-horsepower air-cooled—yes, air-cooled—flat-six engine entirely engineered by Williams Advanced Engineering. The car also features improved aerodynamics and lighter suspension components, as well as the use of lightweight components across the entire structure such as magnesium, titanium and carbon fibre.

The result is a super powerful Porsche 964 that weighs no more than 988 kg.

All Unique As is tradition with Singer vehicles, customers who will order such a modification on their 964 will have access to exclusive components that aren’t available on “regular” Singer 911s. These include bespoke Michelin Pilot Sport Cup 2 tires, 18-inch magnesium wheels, Brembo brake callipers with carbon composite rotors, a magnesium six-speed manual gearbox from Hewland and unique suspension damping from EXE-TC.

Singer wishes to not disclose sales prices to the public, since each car will have a different price tag depending on its configuration. But expect it to be expensive. All modifications will occur in the U.K. at the Williams campus in Oxfordshire. And only 75 of these stunning machines will be produced. At least we’ve got these mind-blowing images to quench our thirst.
